Attached is a rough Network diagram of what I want to achieve but cant find a way:
A client over the internet connects to 216.1.2.2(internet IP on R2) but this gets automatically redirected to 216.3.3.6(internet IP of Server on Lan behind R1) so they access.
so what I actually want is that the internet IP of 216.1.2.2 is automatically redirected to 216.3.3.6.
Lan behind R1 is currently setup properly with appropriate nat and accessible but I want it to be accessible both way ie
Server C with internet ip of 10.0.0.3 - 216.3.3.6 should be accessible using both 216.3.3.6 and 216.1.2.2 as well.
I have tried all posible configurations and have search the whole internet but can't find anything to solve this issue.
I need only to setup R2 as R1 is already setup with regular nat and static route.
Would appreciate any help as soon as possible.
